When reflecting on his rabbinic career thus far, Rabbi Blech is most proud of “having been enabled - through my books, sermons, classes at Yeshiva University and personal contacts - to change lives and bring many thousands of people closer to Hashem. That is a blessing beyond words.”

He adds further: “I will always be grateful for the opportunity that was afforded to me to combine my rabbinic career with a teaching position at YU - which I still maintain to this day after retiring twenty years ago from the active congregational Rabbinate. I sincerely urge all my colleagues to seek similar educational opportunities in order to maximize their personal growth and satisfaction from a rabbinic career."
